Sounds stupid, but I've seen our little bantam roo in action and didn't expect these eggs to be fertile!!! Now I hear peeping from the nest box, it's day 20. I haven't prepared a thing for them. 1? Should I lock the others out of the coop until the chicks hatch? 2? I know I need to set up a separate place for mom and chicks, I have a place in the run to do it but will the chicks stay warm enough at night? 3? I need chick starter but should I get medicated? I'm assuming mom will eat some too. ANY advice is helpful. As you can see, I'm in a bit of a panic...my first time THANKS!
